Description

The method for repairing and mending that is used for large-scale inflammable and explosive agent reservoir bottom land crack
Technical field
The present invention relates to the method for repairing and mending in the storage tank bottom land crack in a kind of chemical production equipment, relate in particular to a kind of method for repairing and mending that is used for large-scale inflammable and explosive agent reservoir bottom land crack.
Background technology
In the Chemical Manufacture industry, those large-scale storage tanks that are used to store chemical mediator or other medium in use for some time, the crack can appear in the bottom land of storage tank.If repair processing to these cracks are untimely, can cause the leakage of medium, not only production is impacted, and because what store in the storage tank is inflammable and explosive chemical mediator mostly, its leakage can cause certain potential safety hazard.
At present, when large-scale inflammable and explosive agent reservoir bottom land crack is repaired, for preventing the burning and the blast of storage tank bottom leakage, usually the method that adopts is with large-scale crane storage tank to be hung original position, subsequently repair by welding is carried out in the bottom land crack, after the repairing, again storage tank is pressed to original position, though this method for repairing and mending has been avoided the possibility that storage tank bottom leakage is burnt and exploded in the mending course, adopts this method relatively to waste time and energy gigantic project.Perhaps exactly bottom land is carried out integral replacing, like this production cost will increase.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method for repairing and mending that is used for large-scale inflammable and explosive agent reservoir bottom land crack, adopts this method for repairing and mending to need not when repairing storage tank to be hung original position, can repair the bottom land crack.
For solving the problems of the technologies described above, the present invention has adopted a kind of method for repairing and mending that is used for large-scale inflammable and explosive agent reservoir bottom land crack, this method comprises the emptying of storage medium in the storage tank of repairing early stage and the cleaning of storage tank inside, adopts following steps to operate simultaneously:
Step 1: offer aperture K respectively in the both sides that bottom land need mend a split 1And K 2, offering aperture K 1And K 2The time, add water cooling.Because the oil sand of bottom land is inflammable and explosive chemical substance, high temperature during perforate or Mars may cause the burning and the blast of these materials, constantly add the effect that water can play cooling, thereby prevent the burning and the blast of chemical substance;
Step 2: with aperture K 1, K 2After the tapping, connect pipeline respectively, at aperture K 1Pipeline be provided with valve F 1, at aperture K 2Pipeline be provided with valve F 2, be connected on aperture K 1With aperture K 2On pipeline respectively with house steward welding, house steward's pipeline opening K 3Manhole through storage tank is connected to the storage tank outside;
Step 3: to pipeline opening K 3Feed steam, reach valve-off F after the certain limit value to the bottom land temperature 1And F 2, repair by welding is carried out in the bottom land crack;
Step 4: in the process of repair by welding, by valve F 1And F 2The adjusting of opening and closing keeps the certain quantity of steam of bottom land;
Above-mentioned steps two to four is by at aperture K 1And K 2On the valve F that connect 1And F 2Come to keep certain quantity of steam at the bottom of the control flume, between bottom land and oily sand, form a separation layer, thus the spark that produces can avoid the inflammable and explosive chemical substance of oil in husky to touch the repair by welding crack time and the blast and the burning that cause.
Step 5: after the bottom land crack is repaired and finished, with pipeline and the valve F that is connect 1And F 2Remove, and with plug with aperture K 1And K 2Stop up sealing.
For guaranteeing the security implementation of this method for repairing and mending, to pipeline opening K 3Feeding steam has corresponding standard, exactly in the bottom land temperature reaches 50--70 ℃ of scope behind the numerical value, and should be with valve F 1And F 2Close.
Owing to adopted the method for repairing and mending in storage tank bottom land of the present invention crack, by offering aperture in the both sides, crack, and on aperture external pipe and valve, in pipeline, feed steam, thereby steam is filled in separation layer of formation between storage tank bottom land and oily sand, reaches the effect of the spark that produces when avoiding the husky interior inflammable and explosive chemical substance of oil to touch the repair by welding crack.Adopt the method for repairing and mending in storage tank bottom land of the present invention crack, when repairing the bottom land crack, need not storage tank is hung original position, not only saved a large amount of operating times, alleviated working strength, and safe and reliable.
